ClGAR-BUNCHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 663,964, dated December 18, 1900.

Application filed April 30, 1900. Serial No. 14,818. (No model.)

T0 at whom, it may concern: I

Be it known that I, HERMANN O. GREvE, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Oigar-Bunching Machines; and I do declare the following to be a ful],clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had totheaccompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to cigar-bunching machines; and it consists of various improvements of the cigar-bunching machine shown and described in Letters Patent No. 631,297, granted to myself August 22, 1899.

The object of the present invention is to provide means for obtaining various necessary adjustments in said machine, as will be hereinafter fully described in the specification and pointed out in the claims.

In the accompanying drawings, Figure 1 is a top plan view of my improved cigar-bunching machine. Fig. 2 is a side elevation thereof. Fig. 3 is a longitudinal sectional View on the line a: a: of Fig. 1. Fig. 4 is a bottom plan view. Fig. 5 is a sectional view on the line y y of Fig. 1.

The letter A designates the frame, which is of cast-iron or any suitable material and is of "oblong rectangular form and a portion of the sides of which project upwardly, as shown in Fig. 2.

B is a cloth, which is preferably of an elastic nature. .The longitudinal edges of this cloth are free or disconnected from any part of the machine in order that it may be adjusted. The end B of this cloth is secured to a transverse rod 0 and is passed around a stationary transverse bar 0, which may be rigidly secured to the sides of said frame. The other end B of the cloth B passes around a tube or sleeve D, which is mounted on a transverse rod D, suitably mounted in the frame. The extreme rearward end of said cloth is secured to a transverse rod E, which is rigidly held between two rods E, the ends of which are screw-threaded and passed through an end wall of the frame A and receive adjusting-nuts F, by means of which the cloth B may be adjusted to present a proper operatingsurface. The cloth B is mounted above a series of rollers G, which are loosely mounted in recesses G in the upper portions of the sides of the frame, so that the said rollers G may have a more or less rotary movement when a bunch is being rolled over the tablecloth B. The extreme forward one G of said rollers, it will be seen, is of a smaller diameter than the others and occupies a position between the bar O and the first one of the larger rollers G. This small roller G is also loosely mounted in order that it may have some yielding movement when the bunch is passed over it on the way to the table proper. The table proper consists of that portion of the cloth B which lies above the rollers G, and the object of placing the small roller G" in such position is to afford a proper passage of the bunch onto the table, said passage being gradual and free from any abrupt obstruction.

D designates a concaved plate which 00- cupies a stationary transverse position in the forward end of the frame and has a depression D the front end of which terminates substantially on a plane with the front end of the cloth B, which end lies above the crossbar O, as hereinbefore stated.

H designates a ribbon which lies on the top of the cloth'B and is of less width than said cloth, as shown in Fig. 1. The front end H of said ribbon is secured to the front end of the frame by means of a transverse bar I, which is screwed to the top of the frame, with the end of the apron between it and the upper edge of said frame. The upper edge of said end of the frame and the contact side of said bar I are suitably corrugated in order to secure a firm hold on the end of the apron. The other end H of said apron passes over the sleeve D, above the cloth B, and then around a sleeve 1, which is loosely mounted on a bar I", secured to the frame, and the extreme end of said apron is secured to an adjusting-bar J, which lies across the rear end of the machine, as shown in Figs. 1 and 4. The bar J consists of two parts, which are hinged in the middle to the inner end of a central adjusting-screw K. The outer ends of said bar J are similarly connected to outer adj usting-screws K. These screws K pass through the end of the frame and are provided with inner and outer nuts K and K, by means of which adjustments are obtained. The range of adjustment which may be given the apron H is shown in Figs. 1 and 4, where it will be seen that the apron may be adjusted in its longitudinal center and also along its side edges. It may be made tighter or looser in one part without affecting the other part, or the tension may be made uniform throughout. This adjustment is useful for applying a greater or less pressure to the center of the bunch, as circumstances may require. The forward end of the apron H rests upon a roller L, which is mounted in the arms L, which are pivoted at L to side brackets M, which constitute a carriage for said roller L. The rearward ends of said arms L are bifurcated and receive adjusting-screws N, which enter the said brackets M, and thus the roller L may be given some up-and-down adjustment to vary the area or depth of the pocket P in said apron. This pocket P, it will be seen, is formed when the roller L is moved to its extreme front position, which brings the apron into the depression D in the plate D.

O designates two parallel tracks or side bars the ends of which are journaled in brackets O, which project from the sides of the frame. Upon these rods or tracks the brackets M are mounted to move back and forth, as shown in Fig. 3. In this figure of the drawings the apron H is in a position to receive the binder and filler from which the bunch is made. The filler is placed in the pocket P and the binder on top of the apron H immediately in front of said pocket P. The carriage is then moved by means of the transverse handpiece Q, which extends from each of the brackets M. This movement of the carriage to the other end of the machine carries the pocket P over the table and applies the necessary compression to the bunch.

I have found in practice that better results are obtained by enabling the rollers G to have some slight yielding movement when the bunch is brought in contact therewith. The rolls G being free to turn, there is a certain yielding thereof as the bunch passes over each of said rollers. In my former patent hereinbefore referred to these rollers are mounted rigidly, and when the bunch is brought in contact with said rigid bars the impact causes a more perceptible compression of the filler than is necessary or desirable. This is overcome to a highly satisfactory degree by providing means forenabling said rollers to move to a greater or less extent when such impact is made.

The rear end of the machine is provided with a cover R, which is detachable from the frame. This cover R is removed from Fig. 1. As shown in Figs. 2 and 3, it has an upright plate R, which is adjust-ably secured to the cover by a thumb-screw R. This plate provides a space S, into which the bunches fall as they are rolled from the table.

Having described my invention, I claim-- 1. In a cigar-bunching machine, the combination of a supporting-frame, having a depression in one end thereof, of a series of transverse rollers in said frame, one of said rollers being mounted adjacent to the depression in said frame, and below the plane of the other rollers, and forming a gradual passage from said depression, a cloth placed on the upper side of said rollers, an apron resting on said cloth, a traveling roller engaging the under side of said apron and forming a traveling pocket therein in which a bunch may be carried over the table, the said bunch being subjected to a yielding pressure as it is brought in contact with each of said rollers which is due to the partial rotation of said rollers, substantially as shown and described.

2. In a cigar-bunching machine, the combination with a supporting-frame, of a table comprising a series of transverse rollers loosely mounted in said frame, a table-cloth laid over the upper side of said rollers with its longitudinal edges free, a depression in said frame adjacent to said cloth and forming a gradual ascent to said cloth, an apron resting on said cloth, a roller engaging with the under side of said apron and providing a traveling pocket therein in which a bunch may be carried over the table, means for adjusting said roller to vary the area of said pocket, and adjusting devices for varying the tension of the table-cloth, substantially as described.

In testimony whereof I afiix my signature in presence of two witnesses.
